Getting java enum by name [duplicate]

Question

Is it possible to get an enum by searching on its name instead of value ? For example :

public enum MyEnum { TOTO("some value", 1); ZOZO("some other value", 2); }

And what I want to do is a getter like :

public static MyEnum getByName(String str) { [...] }

So I can do :

MyEnum foo = MyEnum.getByName("TOTO"); MyEnum bar = MyEnum.getByName("ZOZO");

Use the built-in MyEnum.valueOf(name).

Each Java enum has method valueOf(String name) which returns enum by name.

MyEnum foo = MyEnum.valueOf("TOTO"); MyEnum bar = MyEnum.valueOf("ZOZO");

What is wrong with this answer?

Okay I misunderstood the javadoc... But in this case wouldn't it be better to use MyEnum.valueOf(MyEnum.class, "TOTO") ?

@Dynamite There is no reason for that. Trust me :)

@Dynamite that would only be useful if the first parameter were only known at runtime, e.g. you've just got a variable Class<? extends Enum<?>> someClass.
